No requirement,no glitch. And something I don't wish to do.

 I have been having promotions / discounts, on a fairly regular basis, over the past two years.

Even with 50% more listings, turnover has been difficult to maintain. But the sales work for me.

Reducing prices doesn't seem to work, unless there is a red tag and a price with a slash through it.

Ebay also sends promo emails to viewers and watchers of items.

If there is stock I want to see gone, or is easily replaced, it makes sense in these times.
